Our Vision to Solve Overpopulation A TWO child average will not solve overpopulation. With a two child average per woman (or per man), total population would go up by about two billion more – to nine billion! – before it even levels off! And it would not decline below 8 billion for another 200 years!

Metapopulation: Definition, Theory & Examples Metapopulation Theory. Metapopulation theory states that a large population consisting of a single species is most stable over a large area when it is divided up into smaller subpopulations. These subpopulations take advantage of small, local environments, like your backyard or the park down the street.etapopulation Theory.
